I have the same crash in my apps . IOS 11+ occupy 90 percents

[EricDDK]

My measures is add Director::getInstance()->stopAnimation() and Director::getInstance()->startAnimation(); in applicationDidEnterBackground and applicationWillEnterForeground func , but I haven't update . so I do not know how effective it is。

I notice that there is a line
MyDelegate.swift line 18
which is a swift source code. It doesn't belong to cocos2d-x source code.
So you modified some thing right?
Could you reproduce this bug on your iOS 11 devices?

[deguilardi]

Actually a lot of random crashes will also trigger this error.
The MyDelegate is nothing more than the delegate of the app (where the app starts from).
To you guys have an idea, I could reduce this error rate by 50% when I applied the following patch: 25c2403#diff-4e41f257e5233b8a616f60b0d86b5af8

Because of that missing colon, the app was crashing right there and it was a nightmare to figure it out. But anyways, there are still random things triggering this error.

Guys, any update on fixing this crash? I am having a similar crash on crashlytics for my app as well.

This crash is getting a serious trend in our app, especially after iOS 12, any idea?

update the engine to 3.17.1

I don't think it's a good idea.. Maybe there is the same crash in the latest version.
I met this crash, I move some third sdk initial after the game start, the crash disappear.

@xubing Can you please elaborate your solution a bit?
Which SDK you moved from start?

[deguilardi]

This error is trending like never before. Any updates?

[minggo]

May be should update doCaller in CCDirectorCaller-ios.mm as latest v3 codes

cocos2d-x/cocos/platform/ios/CCDirectorCaller-ios.mm

Lines 142 to 145 in a96ff32

	if (cocos2dxContext != [EAGLContext currentContext])
	glFlush();
	[EAGLContext setCurrentContext: cocos2dxContext];

Well, I can't recompile cocos libs as I am still getting the error #18667 opened almost two years ago.
