I have been working on an application from past 4 months and it’s very much depends on Google Maps on iOS platform. Recently one of my friends raised a concern that what if Apple Inc. decides to use a different Map provider?
It turns out after few searching on internet that Apple is going to replace Google Maps with some new advance 3D maps build by company called C3. (One of the researched resource). Well now I am worried of my already written code,
Should I delay my development work until this new technology gets in? or just wait until Apple announces officially.
Thanks
This is a common dilemma in programming, and there’s a common solution too. Develop your own primitives – whether you need to display overlays, show landmarks, draw polygons and lines, do everything through stubs in your own code. If the underlying platform has to change, you then have a few well-known places to update to the new API.
Be very strict about not accessing the underlying API anywhere that isn’t in your wrapper layer, and it should be straight-forward to change to a different later. Not free, of course, but so long as it’s possible to implement the primitives you need in the new layer, you just need to change those, and can leave the rest of your project untouched.
It’s not worth losing months’ of having a finished project to avoid this situation.
Edit: This approach has another benefit – if you end up writing multiple primitive layers for different APIs, you may be able to let the user pick between them: you may have a (more expensive) higher-quality map layer which you charge for, and a cheap/free one which you don’t – allowing people free access to a lower-quality version, and letting them buy an upgrade to the better maps. Or … there are lots of possibilities. It’s the same pattern some applications take with data-persistence layers, letting people run the same application on top of differing data platforms. There are lots of examples of this patterm.
