Efficient storage and transfer of iOS binary files

A non-transitory computer readable medium having instructions stored thereon that, when executed by a processor, cause the processor to build an application, the building comprising:

• receiving, by a build server, from an application development server, declarative metadata information of the application and a build request to build the application;
• generating binaries of the application by overlaying the declarative metadata information on unsigned binaries of a pre-compiled application, the overlaying comprising adding or substituting the declarative metadata information as deltas in the unsigned binaries;
• signing the unsigned binaries of the application to generate signed binaries of the application and one or more modified files;
• and
• sending, to the application development server, a corresponding signature and the one or more files modified by the signing of the unsigned binaries of the application;
• wherein the build server stores on a storage appliance, to be obtained by an edge server in response to a request from a mobile device to download the application, the corresponding signature, the one or more files modified by the signing of the unsigned binaries of the application, and the declarative metadata information;
• wherein the corresponding signature is compared to a resulting signature based on the signed binaries to verify the authenticity of the application.

A system for building an application, the system comprising:

• a processor coupled to a storage device that stores instructions that, when executed by the processor, implement modules comprising:
• a receiving module that receives, by a build server, from an application development server, declarative metadata information of the application and a build request to build the application;
• a generating module that generates binaries of the application by overlaying the declarative metadata information on unsigned binaries of a pre-compiled application, the overlaying comprising adding or substituting the declarative metadata information as deltas in the unsigned binaries;
• a signing module that signs the unsigned binaries of the application to generate signed binaries of the application and one or more modified files;
• and
• a sending module that sends, to the application development server, a corresponding signature and the one or more files modified by the signing of the unsigned binaries of the application;
• wherein the build server stores on a storage appliance, to be obtained by an edge server in response to a request from a mobile device to download the application, the corresponding signature, the one or more files modified by the signing of the unsigned binaries of the application, and the declarative metadata information;
• wherein the corresponding signature is compared to a resulting signature based on the signed binaries to verify the authenticity of the application.
