This reply has grown quite a bit over the previous 5 6 years. It incorporates a possible repair and annual updates on the issue
2023: Time for the annual criticism: I’ve resorted to importing TestFlight builds, then putting in them to my iPhone and let the “replace” carry over to my Watch. The issue is that even with this extremely sluggish means of creating one thing run on the Watch, you usually get an limitless spinning circle for truly putting in the app on the Watch. What “fixes” that is eradicating the app fully, dropping all app information, then putting in once more solely to run into the identical difficulty once more. I then go to mattress and the following morning it typically works.
What’s “humorous” is that I even bought app updates rejected as a result of the app did not carry over to the tester’s Watch. You then have to open a TSI to elucidate the case, then the TSI man explains the problem (that Apple claims does not exist) to the tester, then it will get rejected once more, you go full circle and normally on the second try the TSI man is ready to persuade the tester that the app installs and that it is a difficulty with the tester’s Watch. On the bug report nonetheless Apple nonetheless claims there isn’t a difficulty with watchOS (clearly all of the upvotes right here should be within the fallacious!). See y’all in 2024 🙂
2022, 5 yr anniversary: For the previous 6 months, I constantly have to take a seat by means of one hour of “Getting ready Apple Look ahead to improvement by way of iPhone” even once I’m not even debugging a Watch app. For sure, this additionally makes it unattainable to run apps on system by way of Xcode. After about 3 hours (principally half my workday) it begins to work. As soon as I take away the app for testing, or unplug the iPhone, I’ve to attend a number of hours once more. By no means in my life have I felt so ineffective as my job at this level principally consists of watching a loading indicator for hours till the method is finished – just for the entire thing nonetheless not working more often than not.
Enjoyable truth: Apple on Twitter claims they use the identical units and instruments for his or her Watch apps.
2021: All Quiet on the Western Entrance. It has been 4 years since my first response. I’ve now had an excellent run throughout December and the primary 2 weeks of January. It was so good that I have never closed the simulator a single time and saved my iPhone related and by no means turned off my mac. This labored for 3 weeks however then my iPhone ended up in a boot loop and restoring fails. I purchased a brand new iPhone and now I can also’t actually join anymore. See y’all in 2022 🙂
2020: At this level I can not even get WCSession to ship information on the Simulators anymore. Message from Watch to iPhone with replyHandler works, message from iPhone to Watch fails with WCErrorCodeWatchAppNotInstalled. Day by day begins with rebooting quite a few occasions and deleting and organising new iPhone + Watch mixtures. Tried on a freshly put in macOS with my good friend’s units and naturally no luck. However it’s clearly my fault. Submitting a bug report does not do something as they solely maintain telling you that every thing is engaged on their finish and they’re going to shut this ticket now. I solely needed to assist.
2019: New iPhone, even worse. Now, each single element in my improvement has modified since 2017 and I am nonetheless caught concentrating on the simulator with each construct. Apple, why?
2018 II: nothing works for me anymore. Contacted Apple a great deal of occasions and Apple Watch appears to have moved to Playground‘s neighborhood because it’s simply loading/working however by no means actually working. Purchased a second Mac, new undertaking, nothing works. Unhappy.
2018: The final couple of days I’ve been actually profitable doing the next:
In your iPhone:
- flip off wifi
- flip off bluetooth
- activate wifi
- activate bluetooth
In your Watch:
- activate flight mode
- deactivate flight mode
Many of the occasions it did not take longer than 30 seconds to get the connection again on monitor. I believe it is the “Watch flight mode”-thing however I by no means change a (considerably) working system so this can be my process any longer. My 2017-reply nonetheless appears to be of assist to some individuals:
2017: If it SOMETIMES reveals, and infrequently does not, it is likely to be on account of the truth that you closed iTunes
I observed what I usually did after reconnecting: closing iTunes. Instantly, the watch turned to be “unpaired”. Reconnecting the USB cable however leaving iTunes open has helped me since.
