Description

When launching any app on iOS 11.0 specifically, the app crashes with the following exception:

[ERROR] The application has crashed with an uncaught exception 'NSInvalidArgumentException'.
[ERROR] Reason:
[ERROR] -[TiRootViewController setNeedsUpdateOfHomeIndicatorAutoHidden]: unrecognized selector sent to instance 0x102814e00
[ERROR] Stack trace:
[ERROR] 0   CoreFoundation                      0x0000000182bc4d74 <redacted> + 148

This is re-produceable using an empty app using 'ti create'. Launches fine on iOS 10, iOS 11.2/11.4, and iOS 12+. Only crashes on iOS 11.0 as far as we can test. This is quite an urgent issue for us, as it is blocking us from releasing a new version to the stores.

I think I've managed to patch this issue using the following in TiRootViewController.m #if IS_XCODE_9 if ([TiUtils isIOS11OrGreater]) { if ([self respondsToSelector:@selector(setNeedsUpdateOfHomeIndicatorAutoHidden)]) { [self setNeedsUpdateOfHomeIndicatorAutoHidden]; } } It no longer crashes on iOS 11 and works on all our test devices we have here.

[~jfinnigan], Does this only occur on a physical device or do you know if it's specifically 11.0.0? I'm using an 11.0.1 simulator (it's the closest I can get from XCode), and can't reproduce the issue. I'll ask the team to try if they have an iOS 11.0.0 device

Verified the fix in SDK 7.5.1.v20181210141225 & 8.0.0.v20181210140414. Closing.
