ios – UIScrollView in UIViewControllerRepresentable – UI freezes when content material touches backside SafeArea


The SwiftUI ScrollView lacks some options I would like and so I created a customized MyScrollView primarily based on UIScrollView wrapped inside a UIViewControllerRepresentable. Whereas this works nice typically I do know got here throughout a really unusual drawback:

When MyScrollView is utilized in a sheet and its content material touches backside SafeArea, the UI freezes as quickly because the ought to be displayed.

The code under exhibits the issue as properly in preview as on the simulator and on units. Please observe that the code is tuned do the show measurement of an iPhone 16 Professional. When working on totally different units one would possibly want to regulate top of the Shade.yellow.

Within the demo code the UI freezes if the Shade.yellow has a top between 738 to 771 pixels. Each different top is ok.

Is there one thing fallacious with my implementation of MyScrollView? When utilizing ScrollView as a substitute, all the things works nice.

Code:

struct ContentView: View {
    @State non-public var showSheet: Bool = false
    
    var physique: some View {
        ZStack {
            Button("Present Sheet") {
                showSheet = true
            }
        }
        .sheet(isPresented: $showSheet) {
            VStack {
                Textual content("Some Header Content material")
                
                MyScrollView {
                    VStack {
                        Shade.yellow
                            //.body(top: 737)   // works
                            .body(top: 738)     // does NOT works

Robotic gripper makes use of measuring tape fingers for delicate object dealing with


Metal measuring tape is an attention-grabbing materials, in that it is inflexible sufficient to carry its form when prolonged, however versatile sufficient that it provides approach underneath stress. Scientists have taken benefit of that twin nature in a intelligent new robotic gripper designed for dealing with fragile gadgets.

Created by Assoc. Prof. Nick Gravish and colleagues at UC San Diego, the mechanical appendage is called “GRIP-tape,” the phrase GRIP standing for “Greedy and Rolling In-Aircraft.” It grasps objects of varied sizes and shapes between two grippy however compliant triangular fingers.

Every of these fingers is product of a few lengths of measuring tape that are laid lengthwise one on high of the opposite, and adhesive-taped collectively in that configuration … in order that they type a single two-layered ribbon that is bent/buckled on the tip of the finger. Two motorized reels – one at both finish of that ribbon – roll it in and spool it out as wanted.

A New Robotic Gripper Primarily based on Measuring Tape is Sizing Up Fruit and Veggie Selecting

By various the path through which every of the 4 reels (two per finger) rotate relative to at least one one other, the fingers could be made longer or shorter, they will rotate an merchandise grasped between them, or they will draw that merchandise in or out, conveyor-belt-style. Your entire gripper may roll back and forth and tilt up and down, swiveling on its robotic wrist.

It’s hoped that after the expertise is developed additional, it could possibly be utilized in fields corresponding to agriculture, for choosing vegatables and fruits with out damaging them. In actual fact, UCLA’s EEWOC (Prolonged-reach Enhanced Wheeled Orb for Climbing) robotic already makes use of a measuring-tape-based magnetic limb for climbing metallic buildings.

”We prefer to search for non-traditional, non-intuitive robotic mechanisms,” says Gravish. “The tape measure is such a beautiful construction due to its mixed softness and stiffness collectively.”

A paper on the research was not too long ago printed within the journal Science Advances.

Microsoft’s huge purchase exhibits decarbonization potential of paper mills


Key takeaways

  • Microsoft has signed a deal for 3.7 million carbon elimination credit over a 12-year interval
  • Challenge developer CO280 will generate the credit by capturing emissions from pulp and paper mills
  • Many U.S. mills are located shut to appropriate geologic storage reservoirs

Might the pulp and paper business be remodeled into an engine for carbon elimination? That’s the tantalizing risk raised by a deal between Microsoft and CO280, a undertaking developer targeted on capturing and storing carbon dioxide emitted from pulp and paper mills.

The tech large will buy 3.7 million tons of elimination credit from CO280 over a 12-year interval, the developer introduced right now.

The deal follows a smaller contract introduced in December with Frontier, a coalition of corporations that funds early-stage carbon elimination tasks. Help from these two heavyweight backers of carbon elimination will assist CO280 broaden an present pilot retrofit of a Gulf Coast mill to seize round 400,000 tons of carbon dioxide, mentioned Jonathan Rhone, co-founder and CEO of CO280. He wouldn’t share a exact value, however mentioned that the credit would price lower than $200 per ton.

The method has the potential to be “carbon unfavorable” as a result of the feedstock utilized in pulp and paper mills — small-diameter timber and waste biomass from timber operations — comprises carbon captured by photosynthesis. A few of that carbon makes its method to the cardboard packaging, tissue and different paper merchandise mills produce, however a majority results in “black liquor,” a waste materials burned within the mill to generate warmth.

CO280 sends the gases from that combustion by way of a liquid solvent that captures CO2. After a biomass steam boiler heats the solvent to launch the CO2, the system pipes the fuel round 40 miles to a website the place it’s saved underground in a geologic reservoir.

The corporate declined to reveal the exact location of the retrofitted mill.

‘Pleased coincidence’

CO280 has greater than 10 tasks in improvement, in keeping with Rhone. After the primary Gulf Coast undertaking activates in 2029, he estimated that the corporate would add a “couple of million tons” of elimination capability yearly.

CO280 declined to specify the price of the retrofit. Rhone mentioned that it’s within the “a whole bunch of thousands and thousands of {dollars}.”

The corporate’s speedy growth can be made doable by what Rhone described as a “joyful coincidence”: Many U.S. pulp and paper mills are based mostly on the Gulf Coast, an space that’s already being focused for carbon elimination tasks as a result of it has good choices for geologic storage. Which means there’s present infrastructure for importing and burning biogenic carbon in a area the place the emissions could be saved. Add carbon seize to the equation, and a strong elimination possibility turns into accessible. U.S. pulp and paper mills emit near 90 million tons of CO2 yearly, in keeping with CO280.

“Pulp and paper indubitably goes to be a serious participant within the carbon elimination area,” mentioned Joe Sagues, a researcher at North Carolina State College who research the elimination potential of the business.

Questions on the method

The long-term affect of those retrofits has been questioned, nonetheless. In a submit printed this February, researchers on the non-profit CarbonPlan famous that the last word targets of carbon elimination are to cope with residual emissions from industries that may’t be decarbonized and to attract down extra carbon from the environment. The researchers checked out services that produce ethanol from corn and noticed that even after retrofits of carbon seize tools, the method as a complete stays a web emitter. In that case, embedding elimination within the business can cut back emissions however gained’t ship on the aim of drawdown.

‘A good level to make’

CO280’s first Gulf Coast retrofit will match this sample in that it’s going to seize solely round half of the ability’s biogenic emissions. However ethanol retrofits are more difficult to make carbon-negative, mentioned Sagues: rising corn produces emissions, fossil fuels are used to make the ethanol and the big quantities of biogenic carbon are emitted when ethanol is utilized in autos. In pulp and paper mills, many of the emissions come from biogenic black liquor and could possibly be captured as retrofits unfold. In concept, the business has a long-term path to unfavorable emissions that ethanol lacks.

“I feel it’s a good level to make,” mentioned Rhone of the CarbonPlan critique. Current monetary incentives, together with the comparatively excessive value of elimination credit and federal tax incentives, present a basis for getting began, he added. Extra expansive seize methods can then comply with if the economics work.  “In the end the aim is to get to utterly web zero mills, however these are advanced tasks,” mentioned Rhone.

The tax incentives embrace a tax credit score for carbon storage referred to as 45Q, which was launched within the first Trump administration and strengthened as a part of the Inflation Discount Act (IRA), in addition to assist from the Division of Power. The Trump administration has not made its place on carbon elimination clear, however the business has watched nervously as key members of the DoE’s Workplace of Fossil Power and Carbon Administration, which oversees a number of elimination initiatives, departed after the election.
