Swift package manager plugins allow us to customize some actions during build time to meet more complex compilation requirements, such as code generation.
Building Swift Package as XCFramework
- By
Compared with Xcode project’s Build Settings, Package.swift is much simpler to use. However, when we convert a Xcode framework project into a Swift package, the XCFramework cannot be built successfully.
Integrating Apple Pay to iOS App
- By
Apple Pay is Apple’s mobile payment service. We can use Apple Pay to make a tap-to-pay in physical stores or purchase goods in apps. In addition, the Wallet app in iPhone can manage credit cards, so we don’t need to carry several credit cards.
Integrating Google Pay to Android App
- By
Google Pay is Google’s mobile payment service. We can use Google Pay make a tap-to-pay in physical stores, and we can also purchase goods in apps. In addition, Google Wallet can manage credit cards, so we don’t need to carry several credit cards.
ECDSA Signing and Verifying Examples
- By
Elliptic Curve Digital Signature Algorithm (ECDSA) is a digital signature algorithm (DSA) commonly used for digital signatures. This article will introduce how to use ECDSA to sign and verify in Android and iOS.
GCC Inline Assembly
- By
GCC’s inline assembly allows us to embed assembly code in C code. C code is much more readable than writing assembly code directly.
x86-64 Calling Conventions
- By
Calling conventions refers to the specifications that the two functions should follow when one function calls another function. For example, how to pass parameters and a return value between them. Calling conventions are part of the application binary interface (ABI).
Linker Script
- By
When compiling source files into executable files, GCC compiles source files into object files. Then, the linker links the object files into a executable file with a linker script.
x86 Memory Map
- By
After the x86 PC boots, it will be in real mode. At this time, we can access memory below 1 MB. However, the BIOS also uses some memory. Therefore, we must know which areas the BIOS occupies in order to avoid them.
