CodeForge: DSA Interview Prep
DSA & Coding Interview Prep
Free
Master Swift Data Structures, Algorithms, and iOS Engineering offline on your Mac with real-time code runners and interactive visualizers!
SwiftForge is the premier, native macOS IDE built specifically for iOS developers, Swift engineers, and computer science students preparing for senior technical interviews and honing algorithmic mastery.
Unlike web-based coding platforms, SwiftForge runs completely offline on your Mac. It provides instant code compilation, zero network latency, real-time assertions, and interactive data structure visualizers designed for pure Swift development.
FEATURES & HIGHLIGHTS
• DUAL PRACTICE TRACKS
Master LeetCode-style Data Structures & Algorithms (Arrays, Hash Maps, Linked Lists, Trees, Dynamic Programming, Graphs) alongside real-world iOS Engineering concepts (ARC & Retain Cycles, Swift Concurrency async/await, Combine Publishers, Value vs Reference types, and SwiftUI State).
• EMBEDDED SWIFT CODE EDITOR
Enjoy a high-performance syntax-highlighted code editor with line numbers, customizable font sizes, bracket auto-closing, and automatic local draft persistence so you never lose your progress.
• LOCAL EXECUTION ENGINE
Run Swift Code locally on your Mac using a safe subprocess pipeline. Experience immediate terminal console feedback, runtime error stack traces, execution duration (ms), and stdout logging.
• INTERACTIVE DATA STRUCTURE VISUALIZERS
Gain deep intuition for complex algorithms with dedicated visualizers:
- 2D Matrix & Grid Visualizer for grid search and DP problems.
- Array & Hash Table Visualizers highlighting target pairs and complement matching.
- Stack String Visualizer displaying character streams and stack balance metrics.
- Linked List Visualizers rendering node memory pointers.
- Staircase Height Visualizers illustrating dynamic programming recurrence relations.
• DEVELOPER ANALYTICS & DAILY STREAKS
Build a consistent daily coding habit with automated streak counters, solved challenge badges, run counts, and local JSON profile storage.
• SLEEK GLASSMORPHIC DARK DESIGN
Designed natively for macOS Sonoma & Sequoia with custom dark glassmorphic panels, glowing accent gradients, and fluid split-pane workspace views.
