Re: iOS App Development with MusicXML?

Hi Joyce,

If you are looking for Open Source solutions, I would recommend:
- Verovio (https://www.verovio.org/index.xhtml) : widely used and active community. Downside: currently does not use Native iOS rendering. You’d have to pass through a WebView (as mentioned by Andrew H.).
- GuidoLib (https://github.com/grame-cncm/guidolib/ ): old but very robust with support for native rendering. When coupled to LibMusicXML it can render a variety of formats.

The baseline of features that I’m looking to implement would be a custom view to display and edit written out music (ranging from a few beats without bar lines to whole pages) as well as the ability to export out to PDF and XML files that can be imported into other music apps. I’ve been reading through MusicXML and feel like it will suit my needs but have mostly just familiarized myself with the XML tags and their mappings to music symbols.

As MusicXML is used in so many public products, I was hoping there might be some libraries, open-source code, tutorials, or documentation that I could use as a jumping off point. In particular, I’m interested in any materials specific to iOS development since there are fewer built-in libraries that support functionality like XML parsing and writing. I’m currently looking at OpenSheetMusicDisplay <https://opensheetmusicdisplay.github.io/classdoc/> and VexFlow <https://www.vexflow.com/> and rendering to a WebView, but I’m working in SwiftUI and would prefer writing a renderer from scratch. I’m also open to looking into other notation formats such as MNX if it would provide compatibility with other composition software (Sibelius, Finale, etc.).
