问题
I get a crash log from Crashlytics/Fabric which reads like the following:
function signature specialization <Arg[0] = Exploded, Arg[1] = Owned To Guaranteed> of
MyClass.viewWillAppear (MyClass)(Swift.Bool) -> ()
what does exploded mean for Arg[0]? It's weird that there are two arguments because we're talking about viewWillAppear here - is the first argument the object itself?
回答1:
I got this issue a week ago, and thankfully managed to fix it remotely. I believe it is a parsing issue.
The issue was because I was getting an array of strings from the server, and one of the argument was empty, generating a parsing error of the arguments
["String1", "String2", "String3",]
should have been
["String1", "String2", "String3"]
In your case : Look for what is in your viewWillAppear and check for any parsing/serializing. A bad object returned is probably the root cause of this
