Do I need to install CocoaPods for launch project on device?

[jun chen]

yes, you need to install CocoaPods.

[Dima Avdeev]

And after this, I need to launch Xcode and start's app. Right?

[Dima Avdeev]

In Xcode I need to open this workspace https://github.com/happyjun/KMMExample2/tree/main/iOSDemos/TMM-iOS/TMM-iOS.xcworkspace ?

[jun chen]

yes. you need to
1. run "pod install" in podfile folder
2. double click "TMM-iOS.xcworkspace" file to open this workspace
3. then you should change app sign for yours in xcode and select your ios device
4. you can click to run app in xcode

[jun chen]

@Dima Avdeev can u compile my example successfully and reproduce the crash in ios 7?

[Dima Avdeev]

Sorry, I didn't try yet. But I will try later. Why iOS 7?
At first message mentioned OS version 11.4

[jun chen]

thanks, you can use os version 11.4, since my ios 7 's version is 11.4.

[陈雄]

CodingChen means iPhone7 rather than iOS7，the crash occured on iPhone7 iOS 11
