加载xib crash

Question

之前都是用我自己手机调试（iOS11）都没什么问题，今天用同事（iOS10.3.1）手机build竟然crash了，看了下crash的地方，进入加载xib的地方。所有这样加载的代码都会crash，奇怪！，xib中没有设置file'sOwner,关联了xib对应的class。

[[NSBundle mainBundle] loadNibNamed: nibName  owner: nil options:nil]

完整代码

@implementation ContactInfoDetailView

- (void)awakeFromNib {
    [super awakeFromNib];
    [_iconLabel addCornerWithRadius: 6.f directions: UIRectCornerAllCorners];
}

+ (ContactInfoDetailView *)getContactInfoView {
    NSString *nibName = NSStringFromClass([self class]);
    ContactInfoDetailView *view = [[[NSBundle mainBundle] loadNibNamed: nibName  owner: nil options:nil] firstObject];
    
    return view;
}

log:

Terminating app due to uncaught exception 'NSInvalidUnarchiveOperationException', reason: 'Could not instantiate class named _UIColorAttributeTraitStorage'
*** First throw call stack:
libc++abi.dylib: terminating with uncaught exception of type NSException

已知道原因，由于用了ios11的新特效引起的，ios11可以在Asset Catalogs中添加Color，还以为是xcode的新特性可以直接在xib中使用，然而并不能。。。
