What did you do?

If possible, provide a recipe for reproducing the error.
I've downloaded the latest gomobile version following the instructions online. The version I have now is "gomobile version +2ea7e2c Mon Oct 17 14:21:52 2016 +0000 (android,ios); androidSDK="

I'm trying to build a framework for iOS, which succeeds. But compiling and running against an iOS app fails.

The generated interface contains references that are not defined anywhere.

Error 1: Use of '@import' when modules are disabled

Multiple Errors for every: GoUniverse.h:22:39: No type or protocol named 'goSeqRefInterface'

Example. I've defined a struct in Go:

type Location struct {
    Timestamp int64
    Latitude  float64
    Longitude float64
    Speed     float64
    Course    float64
    Altitude  float64
    Accuracy  float64
}

This generates an interface as this...

@interface GoReachSDKLocation : NSObject <goSeqRefInterface> {
}
@property(strong, readonly) id _ref;

- (id)initWithRef:(id)ref;
- (int64_t)timestamp;
- (void)setTimestamp:(int64_t)v;
- (double)latitude;
- (void)setLatitude:(double)v;
- (double)longitude;
- (void)setLongitude:(double)v;
- (double)speed;
- (void)setSpeed:(double)v;
- (double)course;
- (void)setCourse:(double)v;
- (double)altitude;
- (void)setAltitude:(double)v;
- (double)accuracy;
- (void)setAccuracy:(double)v;
@end

This doesn't compile.

A complete runnable program is good.
A link on play.golang.org is best.

What did you expect to see?

Should compile. Previous version of goMobile didn't use goSeqRefInterface. Output was:

@interface GoReachSDKLocation : NSObject  {
}
@property(strong, readonly) id _ref;

- (id)initWithRef:(id)ref;
- (int64_t)timestamp;
- (void)setTimestamp:(int64_t)v;
- (double)latitude;
- (void)setLatitude:(double)v;
- (double)longitude;
- (void)setLongitude:(double)v;
- (double)speed;
- (void)setSpeed:(double)v;
- (double)course;
- (void)setCourse:(double)v;
- (double)altitude;
- (void)setAltitude:(double)v;
- (double)accuracy;
- (void)setAccuracy:(double)v;
@end

What did you see instead?

Doesn't compile.
