I tested with iOS 12.4 and iOS 14.2.\r\n\r\nThe one concern I have in our Titanium 10.0.0 code is that we call JavaScriptCore's {{evaluateScript()}} and define 2 functions every time we create a {{Promise}} on iOS 12. (We don't do this on iOS 13 and higher.)\r\nhttps://github.com/appcelerator/titanium_mobile/blob/master/iphone/TitaniumKit/TitaniumKit/Sources/Kroll/KrollPromise.m#L35-L49\r\n\r\nThe issue with this is that Apple's docs state that whatever is defined in {{evaluateScript()}} will be added to the global context. JavaScript does allow you to define the same function name multiple times in the same script and the last one always wins. So, I'm curious if this will slowly bloat our JavaScript context on iOS 12.\r\nhttps://developer.apple.com/documentation/javascriptcore/jscontext/1451350-evaluatescript?language=objc\r\n\r\nBut this may be off-topic.

					"body": "Like I said, I can't reproduce it. [~hknoechel], I've even tried running your test code under Xcode and I'm not seeing the \"Window already opened\" warning or anything suspicious in the log. Does the issue only happen on a real device for you? I ask because I've only tested under the iOS Simulator.\r\n\r\nThe only other thing I can think of is that, this may not be so much a bug as really the timing has changed. APIs that have been transitioned to use promises (such as HTTPClient) will start their operation 1 frame later than before. For example, when you open a window, the \"open\" event on iOS is fired before the open-animation starts so that you can position your views before the window is shown. The \"open\" event will still happen at the same time as before, but other async operations that you may kick off in your open listener may start 1 frame later... and if you perform a long blocking operation during the open animation then that may cause the stutter effect you're talking about. It could be that your old code used to perform the async operation initiated by the open listener near immediately and before the open animation started. Honestly, I think that's the only thing I can think regarding what might cause a laggy open animation which means it has nothing to do with the Window.open() promise but more with async operations which proceed it.\r\n\r\nI personally don't object to removing promise support from {{Window.open()}} like APIs, but this was something [~cwilliams] was pushing for. We'd be be removing code for an issue we can't reproduce on our end. (I'm not 100% convinced that this is the actual issue. It clearly hasn't been isolated.)",

The reason it caused the transition issues was that all affected views (somehow) used the {{toImage()}} function to render annotation images, which can probably also be put into a quick reproducible case for everyone now.\r\n\r\nI would suggest to just revert the commit for now, as it doesn't harm any code right now. If Chris / Vijay come up with an actual fix using the new API's (which this commit was meant for), I'd be happy to test that as well.
