src画像を変更し、ルックアップにオーバーレイを追加することで、TVMLCatalog の例に付属する ShowcaseTemplate を変更するだけです。

<carousel>  
     <section>  
          <lockup>  
               <img src="${this.BASEURL}resources/images/templates/gft.jpg" width="500" height="600" />  
               <overlay>  
                    <title>Hello, this is title</title>  
               </overlay>  
          </lockup>  
     </section>  
</carousel>

しかし、オーバーレイは表示されていません

これは XCODE ログが示すものです:

Dec  7 11:25:47  TVMLCatalog[3953] <Error>: ImageIO: CreateMetadataFromXMPBufferInternal  Threw error #203 (Duplicate property or field node)  
2015-12-07 11:25:48.996 TVMLCatalog[3953:3684153] Unable to simultaneously satisfy constraints.  
  Probably at least one of the constraints in the following list is one you don't want.   
  Try this:   
  (1) look at each constraint and try to figure out which you don't expect;   
  (2) find the code that added the unwanted constraint or constraints and fix it.   
  (Note: If you're seeing NSAutoresizingMaskLayoutConstraints that you don't understand, refer to the documentation for the UIView property translatesAutoresizingMaskIntoConstraints)   
(  
    "<NSAutoresizingMaskLayoutConstraint:0x7fcee0564910 h=--& v=--& V:[_TVStackingPosterView:0x7fcee051a1e0(46)]>",  
    "<NSLayoutConstraint:0x7fcee0554000 V:[TVLabel:0x7fcee0561020'Image1'(62)]>",  
    "<NSLayoutConstraint:0x7fcee0564250 V:|-(0)-[TVLabel:0x7fcee0561020'Image1']   (Names: '|':_TVStackingPosterView:0x7fcee051a1e0 )>",  
    "<NSLayoutConstraint:0x7fcee0564720 TVLabel:0x7fcee0561020'Image1'.bottom == _TVStackingPosterView:0x7fcee051a1e0.bottom>"  
)  
Will attempt to recover by breaking constraint   
<NSLayoutConstraint:0x7fcee0564720 TVLabel:0x7fcee0561020'Image1'.bottom == _TVStackingPosterView:0x7fcee051a1e0.bottom>  
Make a symbolic breakpoint at UIViewAlertForUnsatisfiableConstraints to catch this in the debugger.  
The methods in the UIConstraintBasedLayoutDebugging category on UIView listed in <UIKit/UIView.h> may also be helpful.

これまで Swift や Objective-C を使用したことがないことに注意してください。だから私はここで完全に迷っています。どんな助けでも大歓迎です

いくつかの調査の後、既知の問題であることがわかりました。
