是从RAC官网看说明文档的吗?希望能介绍一下您的学习方法...
The “Swift Language Version” (SWIFT_VERSION) build setting must be set to a supported value for targets which use Swift. This setting can be set in the build settings editor.
报这个错 网上的方法都没用 是我的问题还是什么
如题
//创建信号
RACSubject * subject = [RACSubject subject];
//map
// RACSignal * bindSignal = [subject map:^id _Nullable(id _Nullable value) {
// return [NSString stringWithFormat:@"%@-mapValue",value];
// }];
// [bindSignal subscribeNext:^(id _Nullable x) {
// NSLog(@"%@",x);
// }];
// [subject sendNext:@"123"];
//flatmap
// RACSignal * bindSignal = [subject flattenMap:^__kindof RACSignal * _Nullable(id _Nullable value) {
// NSLog(@"value = %@",value);
//
// return [RACSignal return:[NSString stringWithFormat:@"change - %@",value]];
// }];
// [bindSignal subscribeNext:^(id _Nullable x) {
// NSLog(@"flatmap = %@",x);
// }];
// [subject sendNext:@"123"];
RACSubject * s1 = [RACSubject subject];
RACSubject * s2 = [RACSubject subject];
[[s1 flattenMap:^__kindof RACSignal * _Nullable(id _Nullable value) {
return value;
}] subscribeNext:^(id _Nullable x) {
NSLog(@"newSignal %@",x);
}];
[s1 sendNext:s2];
[s2 sendNext:@"123"];
编译时报错Unsupported Swift Version,似乎是因为Result用了swift3的代码,而swift3在XCode12中已经不支持了,因此想问下这个该如何解决呀?
