Is it possible to install iPhone SDK 4 beta and SDK 3 on the same Mac?
1 answer
You can install Xcode (and related iPhone SDKs) to a folder other than Developer, leaving your current iPhone SDK installation intact. For example, you can use "DeveloperBeta". During installation, immediately after choosing which volume to install, click the "Developer" folder entry and select "Other" to select a different folder.
After that, make sure you open the version of Xcode you want and open the .xcodeproj files, because double clicking on .xcodeproj (or other iPhone source files) will probably open the beta version of Xcode by default.
