I'm trying to update my project to work with Xcode 7.0 and after updating my Swift projects I'm getting an error that I don't understand on this line.
let jsonData:NSDictionary = NSJSONSerialization.JSONObjectWithData(urlData!, options:NSJSONReadingOptions.MutableContainers ) as! NSDictionary
The error is
"Call can throw, but it is not marked with 'try' and the error is not handled"
I'm also getting these two errors in my project files...
"linker command failed with exit code 1 (use -v to see invocation)"
and
"error: cannot parse the debug map for "/Users/MattFiler/Library/Developer/Xcode/DerivedData/ePlanner-cqwzlxqgpwaloubjgnzdlomjkfea/Build/Intermediates/SwiftMigration/ePlanner/Products/Debug-iphonesimulator/ePlannerTests.xctest/ePlannerTests": No such file or directory"
Try this code:
You'll need the
try
keyword asNSJSONSerialization.JSONObjectWithData
now throws an error if something failed since Swift 2. Throwing functions need to be marked withtry
ortry!
.Also you'll need the
do { ... } catch
to catch any errors that may occur. This will catch the error and handle it.You might want to read up on the changes in Swift 2 to understand why this happened. Also the WWDC videos will be very helpful.
