Here is some code, that converts NSExceptions to Swift 2 errors.
Now you can use
do {
try ObjC.catchException {
/* calls that might throw an NSException */
}
}
catch {
print("An error ocurred: \(error)")
}
ObjC.h:
#import <Foundation/Foundation.h>
@interface ObjC : NSObject
+ (BOOL)catchException:(void(^)(void))tryBlock error:(__autoreleasing NSError **)error;
@end
ObjC.m
#import "ObjC.h"
@implementation ObjC
+ (BOOL)catchException:(void(^)(void))tryBlock error:(__autoreleasing NSError **)error {
@try {
tryBlock();
return YES;
}
@catch (NSException *exception) {
*error = [[NSError alloc] initWithDomain:exception.name code:0 userInfo:exception.userInfo];
return NO;
}
}
@end
Don’t forget to add this to your “*-Bridging-Header.h”:
#import "ObjC.h"
